Abstract
In a radar device including a transmitting unit for transmitting a transmission signal having plural modulation sections, a receiving unit for receiving a reflection signal obtained through reflection of the transmission signal from a target by an array antenna having plural channels, a mixing unit for mixing the transmission signal with reception signals of the plural channels to obtain beat signals of the plural channels, a frequency analyzing unit for frequency-analyzing the beat signals of the plural channels, and a direction calculating unit for calculating the direction to the target on the basis of frequency analysis results of the plural channels, the direction calculating unit adds correlation matrixes generated from peak frequency spectra of the plural modulation sections to obtain an summed correlation matrix, and calculating the direction to the target on the basis of the summed correlation matrix.
